9 Claims. Cl. 296-44) This invention relates to a window arrangement for vehicle bodies and more particularly to'a window arrangement for vehicle bodies of the type having no pillar structure above the body belt line.

In four-door vehicle bodies ofthe type having no pillar structure above the body belt line, movement of the front and rear doorwindows to open position results'in a conr 2,828,999 Patented vApr. 1, 1958 2 belt line and embodying a power operated front door window arrangement according to this invention, with parts being, broken away for clarity of illustration;

Figure 2 is a view similar to Figure 1 showing the window arrangement in partially open position;

Figure 3 is a view'similar to Figure 1 showing one. of

v the windows in closed position and the other of the away for clarity of illustration;

tinuous window opening from the rear edge of the swing ably mounted ventilation window on the front door to the rear quarter area of the body. In this type of body, the front and rear door windows seal against each other in closed position. This requires that one of the door doors in order to seal against the other of the door windows.

In the window arrangement of this invention, the front door window overlaps the adjacent body pillar in order I with a vertically moving window 39 which seals against to seal against the rear door window in closed position. This requires that the front door window have both forward and rearward movement as well as vertical movement and also requires that the front door window and the ventilation window seal against each other in closed position in order to close the window opening from the rear window to the windshield pillar on the body. Thus, the front door window and the ventilation window must be coordinated in their movement to open and closed positions to prevent interference, since the front door window cannot be moved between open'and closed positions when the ventilation window is in closed position.

This invention, in its preferred embodiments, provides such a window arrangement for the front door of a vehicle body having no body pillar above thebelt line and also provides a manner of coordinating movement of the front door window and ventilation window to open and closed positions to prevent interference between the windows.

An object of this invention is to provide a window arrangement for vehicle bodies having no body pillar structure above the'beltline. A more specific object of this invention is to provide a front door window arrangement for vehicle bodies having no body pillar structure above the belt line whichincludes a swingably mounted ventilation window and a vertically and horizontally moving front door window movable into overlapping relationship with the body pillar. A further specific object of this invention is to provide a front door window arrangement for vehicle bodies having no body pillar structure above the belt line which includes a swingably mounted ventilation window and a vertically and horizontally moving front door Window movable into overlapping'relationship with the body pillar together with means for coordinating movement of the ventilation window and the front door windowto open and closed positions.

These andotherobjects" of this invention will be readily apparent from the following specification and drawings, in which:

Figure 1 is a partial side elevational viewof a'vehicle body having no body 'pillar s'tructureabove the body Figure 8 is a sectional view on the plane indicated by line 8-8 of Figure 7; and

Figure 9 is a sectional view on the plane indicated by line 9-9 of Figure 7.

Referring now to Figure 1 of the drawings, a vehicle body 20 includes a roof 22, a windshield header 24 rigidly mounted on the body, and a windshield 26. A front door 28 provided on each side of the body is hinged v v at its forward edge 30on the body and latched at its rearwmdows overlap the body pillar structure between the ward edge 32 on a body pillar 34 which extends only to the belt line 36 of the body on each side thereof. A rear door 38 provided on each side of the body is hinged at its forward edge on the body pillar 34 and latched at its rearward edge on the body. The rear door is provided the roof rail 40 of the body in closed position and, is movable Within door 38 to open position. The front door 28 is providedwith a ventilation window 42 which is swingably mounted on the door for movement to open and closed positions about a substantially vertical axis. A front door window 44 is vertically movable into and out of a well 46 in the door and movable rearwardly and forwardly of the door into and out of overlapping relationship with the upper edge 48 of the body pillar 34. In the closed position of door windows 39 and 44 and ventilation window .42, the rear edge of door window 44 seals against the forward edge of door window 39, and the rear edge of the ventilation window 42 seals against the forward edge of door window 44. Both door windows have their upper edges sealing against roof rail 40 and the ventilation window 42 has its upper and forward edges sealing against a U-shaped frame 43 which is rigidly mounted on door 28. 2

Since the front door window overlaps the body pillar and seals against the rear edge of the ventilation-window in the closed position of both windows, the ventilation window must be moved to an open position to allow movement of the front door window 44 to open position. Likewise, the front door window 44 must be moved to a fully closed or a fully open position to allow movement of the ventilation window 42 to a fully closed position. This invention, in one of its preferred embodiments, provides. power actuators for moving both the ventiation window 42 and the front door window 44 to open and closed positions and also provides means for coordinating the operation of the power actuators to prevent interference between the windows as each is moved to the desired position.

Referring now to Figure 1 of the drawings, the power actuator for moving the front door window 44 to open and closed positions will be described. A back plateSl) is securedto the inner door panel 52'which defines theinner wall of well 46, and an electric motor ,54 and reduction gear assembly 56 are secured to the back, plate.

A sector gear 58 is secured to a stud 60 pivotally mounted on the back plate with the teeth of the gear in mesh with a spur gear 62 of the reduction gear assembly 56 in order that operation of the motor will rotate the sector gear and stud 60 about the back plate. A lift arm 64 is secured to the sector gear at .66 and to stud 60 and provided with a slot 68 having an enlarged portion 70. A coil spring 72 has one end secured to stud 6 and the other end engaging an offset tab 74 on the back plate to counterbalance thelift arm and thesector gear. A channel member 76 is secured to the inner doorpanel S2 at 78 and 80., .The channelmember is of L-shape, having a substantially horizontally extending portion 82 and a vertically extending portion 84 of arcuate shape, The side walls of the channel member are flanged inwardly at 86 on either side of the channel. H V

Referring now to Figure 4 ofthe drawings. a stud 88 is provided with a shouldered portion 90 extending inwardly within channel 76 and having a diameter less than" the width of the opening defined by flanges 86. A washer,

92 fits against the shouldered portion 94 of the stud and against the outer surface of flanges 86 in engagement with a circular bearing washer 96 positioned on portion 90 of stud 88 within the opening defined by flanges 86 and in engagement therewith. A washer 98 similar to washer 92 fits on portion 90 of stud 88 in engagement with washer 96 and the inner surfaces of flanges 86. A retaining ring 100 securesthe washers. in place on the stud in engagement with each other,,with washers 92 and 98 in; engagement respectively with the outer and inner surfaces of flanges 86. Thus, stud 88 is slidably mounted on channel 76 for movement therealong and removal of the stud outwardly of thechannel is prevented by engagement of washer 98 with the inner surface of flanges 86.

Slot 68 of the lift arm 64 is slidably received .on stud 88 with washers 101 provided on the stud on either side of the lift arm to limit lateral movement of the lift arm on the. stud. Stud 88 .includes spaced flat portions 102 and 104, with similar flat portions being provided on .the stud diametrically opposite those shown in Figure 4. An arm 106 is provided at one end with an opening 107 of a shape similar to the cross section of the stud at fiat por- A front guide channel 150 of U-shaped cross section is provided within well 46 in order to guide the sliding movement of the front edge portion of window 44 as the window moves into and out of the door well. The lower end of the guide channel is secured to an offset bracket 152 bolted to the inner door panel at 154 in order to secure the guide channel in the desired location within the door well. The upper end of the guide channel is secured to a similar offset bracket 155 secured to inner door panel. A rear guide channel 156 of U-shaped cross section has its base 158 welded or otherwise secured to the rear wall 160 of door 28 in order to mount the guide channel within the door well 46. Guide channel. 156

' receives the rear edge portion of window 44 as the window moves into and out of the'well and cooperates with guide channel 150 in assuring that window 44 moves substantially vertically into and out of the door well.

Referring now to Figures 1, 2, and 3 of the drawings, the operation of the power actuator for the front door window 44 will be described. The front door window is shown in fully closed position in Figure l, in partially open position in Figure 2, and in fully open position in Figure 3. To move the front door window from its fully closed position of Figure 1 to its partially open position of Figure 2, motor 54 is operated to swing sector gear 58 and the lift arm 64 clockwise about the pivotal support 60 on theback plate. This swinging movement of the lift arm causes slot 68 of the arm to move stud 88 forwardly within the horizontally extending portion 82 of channel 76. Since armportion 136 of arm 112 has a pivotal connection with the lower edge of the window and with stud 88, movement of stud 88 within the horizontally 1 extending portion 82 of channel 76 will cause arm portions 102 in order to rigidly secure the arm on the stud.

A similar arm 108 is provided at one end thereof with an opening 110 of a shape similar to the cross section of the stud at fiat portions 104 in order to secure the arm on the stud in spaced relationship toarm 106. An arm 112 is provided with an aperture 114 intermediate its ends in order to rotatably mount the arm on the stud between arms 106 and 108. e I

Referring now to Figures 1 and Sthe. other end of arm 108 rotatably mounts a stud 118 which is slidably and rotatably received in a channel 120 of U-shaped cross section. The upper and lower legs of the channel are flanged inwardly at 122 to fit within a circular groove 124 provided on stud 118 and prevent removal of the stud from within the channel. Channel 120 is secured within a support channel 122 and the upper leg 125 of the support channel is welded at 126 to the lower frame member 128 of the doorwindow frame 130.

Referring now to Figure 1 of the drawings, the other end of arm 106 rotatably mounts a stud 132 similar to stud 118 and received within a channel 134 similar to channel 120. Channel 134 is secured to the inner door panel 52 at 137 adjacent each end'of the channel. One arm portion 136 of arm 112 is pivotally secured at 138 to an angular bracket 140 which is welded or otherwise secured to the lower window frame member 128 of the door window frame 130 as shown in Figure 9. The other arm portion 142 of arm 112 mounts a roller144 similar to roller 118 and received within a channel 146 similar to channels 134 and 120. Channel 146 is secured to the inner door panel 52 at 148 adjacent each end 0 thfi channel. r

tion 136 to move the door window 44 from its closed position to its partially open position. This will move the rear edge portion of the window from overlapping relationship with the upper edge 48 of door pillar 34 and will locate the window substantially in vertical alignment with the openings of guide channels 150 and 156.

During this movement of the door, stud 144 of arm portion 142 moves forwardly within channel 146, and studs 118 and 132 of arms 108 and 106, respectively, move forwardly in channels and 134. Upon continued rotation of the sector gear and lift arm in the same direction, slot 68 of the lift arm moves stud 88 downwardly along the arcuate portion 84 of channel 76. This causes arm 108 and arm portion 136 of arm 112 to move the window downwardly into the door well 46 within the front and rear guide channels and 156 as arm portion 142 of arm 112 and arm 106 control the displacement of arm portion 136. and arm 108 relative to each other by sliding in channels 146 and 134, respectively. As the window moves downwardly within the door well, arms 106 and 108 move into alignment'with arm 112 and then the arms 106 and 108 and arm'112 cross each other as the window moves to its fully open position of Figure 3. When it is desired to move the window 44 from its fully open position of Figure 3 to its partially open position of Figure 2, motor 54 is operated to swing sector gear 58 and the lift arm 74 counterclockwise about their pivotal support 60 on the back plate. This causes slot 68 of lift arm to'move stud 88 upwardly within the arcuate portion 84 of channel 76 to move the window to its partially open position of Figure 2. During this movement of the window, arms 106 and 108 move into alignment with arm 112 and then the arms 106 and 108 and arm 112 cross each other, with arm ,portion 136 of arm 112 and arm 108. operating to move the window out of the well as arm portion 142 of arm 112 and arm 106 slide in their respective channels to control the displacement of arm portion 136 of arm 112 and arm 108 relative to each other. Upon continued rotation of the lift arm and the sector gear in the same direction, slot 68 of the lift arm moves stud 88 rearwardly along the horizontally extending portion 82 of channel76 to cause arm portion receives the glass panel.

Referring now to Figure l of thedrawings, the'ventilationwindow 42 includes a window frame 162 which A bracket 164 is secured at 1 66 to an upperpanel member 168 of door 28. Bracket 164 supports a gear reduction-assembly 170 which includes a spindle 172 secured to the lowerframe member 174 of the ventilation frame 162. An offset bracket 176 secured in a suitable manner to bracket 164 supports a motor 178 which isconnected to the gear reduction assembly through a resilient coupling 180. Upon rotation of motor 178 in the desired direction the ventilation window 42 willmove to open and closed positions about a substantially vertical axis defined by spindle .172 and po$itioit in overlapping. relationship with the. upper... edge with this measurement indicating the angular relationship between the plane of the left hand-ventilation window a pivot between the upper edge of frame 162 and door to prevent interference between thepwindows. [This coordination feature of the invention is provided by an electrical circuit interconnecting motor.54 of the door window actuator and motor 178 of the ventilation window actuator, and including a number of limit'switches contactable by the lift arm 64 and. spindle 17 2-as the respective windows move to open andclosed positions.

Figure 6 is a circuit diagram showing the circuit for coordinating movement of the windows. Referring now to this figure of the drawings, a battery 184 supplies power to'a conductor 186. A number of switches are connected with conductor 186 and each switch is located on the inner door panel of either the right or left hand door in a position to be operated by either the driver or a front seat passenger.

The circuit also includes a number of limit switches which are mounted on the right hand and left hand. door inner panels andare adapted to be engaged either by the left arm64 for each door window 44 or by a suitable cam on spindles 172 of each ventilation windowpower actuator. Each of these switches is a single polo .double throw switch resiliently biased to close one set of con tacts and operatedeither by the lift arm or by the cam onthe spindle to open the one set of contacts and close the other set of contacts.

A conductor 318 extends from conductor 292 to switch contact 248 and conductor 318' extends from conductor 292 to switch contact 248'. A conductor 320 extends from switch contact 246 to conductor 290 and a conductor 320 extends from switch contact 246' to conductor 290'.

The circuit is shown with all of the windows in closed position. Assuming now that the driver desires to open 6 the left hand ventilation window, he closes switch 206 to switch contact 208 to complete a circuit to the opening winding 286 of the left hand ventilation window motor 178through conductor 284. The right. hand ventilation window may be similarly opened by a front seat passenger. Assuming now that the driver desires to openthe right hand ventilation window, switch 200 is closed to switch contact 202 to connect conductor 186 with condoctor 282 tocomplete a circuit to conductor 284' and the opening winding 286 of the right hand ventilation window motor to open the window. Thus, it is possible for the driver to open either the left hand ventilation window or the right hand ventilation window to any position when the door windows are in closed position and also possible for a front seat passenger to open the right hand ventilation window to any position when the righthand door window is in closed position.

Assuming now that the driver desires to open the left hand door window and that the left hand ventilation window I is in closed position. The driver closes switch 194 to switch contact 198 so as to connect conductor 186 with conductor 280. Current will flow from conductor 280 through conductor 321 to switch contact 240 of switch 226. Since switch226 is closed to contacts 238 and.240;whentheleft hand ventilation window is opened less than 20, switch contact 238 will be connected with switch contact 266 by conductor 306. Since switch 256 is closed to contacts 266 and 268 in all positions of the window except for fully open position, the switch will connect contact 268 with conductor 310 which is connected to the opening winding 286 of the left hand ventilntion window motor 178 through conductor 284 to 'open this window. As soon as the left hand ventilation window has opened 20, switch 226 will open contacts 238and 240 and close contacts 242 and 244. This will brealcthe circuit to the'left hand ventilation window motor 178 and closethe circuit to the opening winding 304 of the left hand door window motor 54 through conductor 302 to open the left hand door window.

Upon movement of the left hand ventilation window to an opened position of 20, switch 224 will open contacts 230 and 232-and close contacts 234 and 236 so as to complete a circuit to the closing winding 300 of motor 54 through conductors 276 and 298. Thus, the driver can either open or close the left hand door window at will by movingswitch 194 respectively to contact 198 or contact 196 when the left hand ventilation window in opened 20, since switches 224 and 226 will close the circuits to theclosing winding 300 and the opening winding 304 of motor 54. As previously mentioned, when the left hand ventilation window is-moved to a position of 20 with respect to the plane of the windowopening, theopening aazsmcc winding 286 of motor 178 will be deenergized. However, if the driver desires to move the left hand ventilation window to a more open position he closes switch 206 to.switch contact 208 so as to connect conductor 186 with conductor 284 to energize the opening winding 286 of motor 178.

As long as the left hand door window is not moved to a fully open position the left hand ventilation window cannot be moved to a closed position less than 20 with respect to the plane of the window opening. Thus, if the left hand ventilation window has been opened to a 20 position as previously described, and then the driver moves switch 206 so as to close contact 21.0, a circuit will be completed from conductor 186 to conductor 290. Since switch 228 is closed to contacts 250 and 252 when the left hand door ventilation window is opened 20 or more, the closing winding 316 of motor 178 will be energized to close the ventilation window. However, as soon as the ventilation window has closed to a position less than 20, switch 228 opens contacts 250 and 252 to deenergize the closing winding of motor 178 and close contacts 246 and 248 so as to connect conductors 320 and 318 with'conductor 290. Conductor 318 is connected to conductor 292. Since switch 256 is only closed to contacts 270 and 272 in the fully open position of the left hand door window, a circuit cannot be completed to the closing winding 316 of motor 178 by means of conductors 317 and 312. Since switch 254 is closed to contacts 262 and 264 only when the left hand door window is in fully closed position, a circuit cannot be completed from conductor 292 to conductor 312 so as to energize the closing winding 286 of motor 178. Thus, it is impossible to close the left hand ventilation window to a position less than 20 with respect to the plane of the window opening as long as the left hand door window is not in fully closed or fully open position. Whenever the left hand door window is in fully open position, switch 256 will be closed to contacts 270 and 272 so as to energize the closing winding 286 of motor 178, as previously described, and whenever the left hand door window is in fully closed position, switch 254 will be closed to contacts 262 and 264 to energize the closing winding 286 of motor 178.

The circuits for the right hand door window and the right hand ventilation window are the same as those for the left hand door window and the left hand ventilation window previously described. Since the same numerals are used for both circuits no further description will be given of the circuits for the right hand door window and the ventilation window. The circuit also includes a remote control door window switch 188 and a remote control ventilation window switch 200 so as to allow the driver to open and close the right hand door and ventilation windows. Since conductor 274 connects switch contact 190 with conductor 276' of the right hand door window, movement of the control switch 188 so as to close the circuit to switch contact 190 will operate in the same manner as closure of the right hand door window switch 194 to switch contact 196. Therefore, it is believed obvious that the circuits will operate in the same manner as previously described in conjunction with the left hand door window switch.

Similarly, closure of the door window switch 188 to contact 192 will completc a circuit to conductor 280' of the right hand door window circuit by means of conductor 278. This circuit will also operate in the same manner as closure of the right hand door window switch 194' to switch contact 198 and therefore no further description will be given of the operationof the remote control door Window switch. Basically, the remote control door window switch connects the circuit of the right hand door window with conductor 186 in the same manner as switch 194 to allow the driver to operate the right hand door window. The remote control ventilation window switch 200 operatesin the same mamieras the remote control door window switch 188. Closure of this switch to contact 202 will connect conductor 186 with conductor 284 by means of conductor 282. Similarly, closure of switch 200 to switch contact 204 will connect conductor 186 with conductor 290' by means of conductor 208. Thus, the remote control ventilat ion window switch will operate to connect the necessaryfconductors of the right hand circuit with conductor 186 in order to energize the desired winding of the ventilation window motor 178. v

Referring now to Figures 7 through 9 of :the drawings, a manually operated type of actuator for both windows will be described. The actuator linkage for the front door window 44 is substantially the same as that previously described, and therefore the same numerals have been used. Instead of having the lift arm 64 secured to a sector gear 58 which is driven by a motor 54, the lift arm 64of this arrangement is provided with a lateral extension 400 which is pivoted at 402 to one end of a shiftable link 404. A back plate 406 mounted on the inner door panel 52 within the forward portion of the door pivotally supports a sector gear 408 at 410. The other end of link 404 is pivoted to the sector gear at 412.

A stub shaft 414 pivotally mounted on the back plate, as can be seen in Figure 8 has secured thereto in spaced relationship a full toothed gear 416 and apartial'toothed gear 418. The gears are rigidly secured to the shaft for movement therewith. An operating handle 420 is secured to a shaft 322 rotatably supported by the door inner panel 52 and the back plate 406. A gear 324 is secured to the shaft 322 in mesh with gear 416 whereby manual rotation of the handle will drive gear 416 and in turn gear 418. A sector gear 326 is pivotally mounted on the back plate at 328 and an arm 330 secured to the sector gear includes a slot 332 which slid-ably and rotatably receives a stud 334 secured to the end of a rack 336. Rack .336 is slidably mounted in a channel .338 secured to the door inner panel and meshes with a spur gear 340 which is in mesh with the gear reduction assembly 170 of the ventilation window actuators. Bothsector gears 408 and 326 i are adapted to mesh with the partial toothed gear 418,

with sector gear 408 adapted tomesh with toothed portion 341 of gear 418, and gear '408 adapted to mesh with either gear portion 342. or gear portion 344 of gear 418.

Both of the windows are shown inclosed position and the sector gears 408 and 326 andpartial toothed gear 418 are shown in their respective positions when the windows are in closed position. Assuming now thatit is desired to-move the door window 44 to open position, handle 420 is manually rotated in a counterclockwise direction so as to rotategears 416 and 418 in a clockwise direction. Since sector gear 326 is in mesh with gear portion 342 of gear 410 while sector gear 408 is positioned between toothed portions 341 and 344, rotation of gear 418 in a clockwise direction will rotate the sector gear 326 in a counterclockwise directionto shift rack 336 rearwardly of the body and move the ventilation window 42 to a partially open position while the door window 44 remains in closed position. In the arrangement shown, this partially open position of the ventilation window isan angular position of 45 degrees with respect to the plane of the window opening. Uponfurther rotation of gear 418;in a clockwise direction, sector gear 326 will be positioned betweentoothed portions 342 and 344 while sector gear 408 will mesh with toothed portion 341 of gear 418.

Thus, continued rotation of gear 418 in a clockwise direcdoor ind w 4 t0 ll'v p n Posit on. v ntila ion nd 42 will remain in its partially open position. Further rotation of gear 418 in a clockwise direction moves sector gear 408 out of engagement with toothed portion 341 of gear 418 to a position between toothed portions 341 and 342 while sector gear 326 comes into engagement with toothed portion 344 of gear 418 to move the ventilation window 42 to fully open position.

When it is desired to move both of the windows to closed position, handle 420 is manually rotated in an opposite or clockwise direction so as to rotate gears 416 and 418 in a counterclockwise direction. Initially, sector gear 326 is in engagement with toothed portion 344 of gear 418 to move the ventilation window from its fully open position to its partially open position of 45 degrees with respect to the plane of the window opening. During this movement of the ventilation window, sector gear 408 is positioned between toothed portions 342 and 341 and the door window 44 remains in its fully open position. Upon further rotation of gear 418 in a counterclockwise directon sector gear 408 comes into engagement with toothed portion 341 of gear 418 to move the door window 44 from its fully open position to its fully closed position as described previously in conjunction with Figures 1 through 3 of the drawings. During this movement of the door Window to fully closed position, sector gear 326 is positioned between toothed portions 344 and 342. Upon further rotation of gear 418 in a counterment with toothed portion 342 of gear 418 to move the ventilation window to its fully closed position. During this movement of the ventilation window to its fully closed position, sector gear 408 is positioned between toothed portions 341 and 344. 0

Thus, this invention provides a window arrangement for four-door vehicle bodies of the type having no pillar structure above the body belt line which includes a front door window overlapping the body pillar in order to seal against the rear door window and also a swingably mounted ventilation window sealing against the front door window. The invention also provides means for coordinating movement of the front door window and the ventilation window to open and closed positions to prevent interference between the windows. In the arrangement shown in Figures 1 through 6 of the drawings, .the ventilation window is movable to a partially open position of 20 degrees with respect to the plane of the window open ing in order to allow opening and closing movement of the front door window. However, this angular position may be less than 20 degrees or greater than 20 degrees depending on body conditions. Similarly, in the arrangement shown in Figures 7 through 9 of the drawings, the angular position of 45 specified as the partially open position of the ventilation window may be greater orless than 45 depending on body conditions.

While a specific embodiment of this invention has been shown and described, various changes and modifications may be made within the scope and spirit of the invention.
